Understanding how heat fluxes diffuse in objects with nanometric dimensions has a double interest. First, to better evacuate the heat generated in nanoelectronic technologies. But also, for applications in energy recovery such as thermoelectricity. In this case, we wish to minimize the thermal conduction of the materials to reinforce their conversion efficiency.
The IEMN in collaboration with the Centre d’Énergétique et de Thermique de Lyon has quantified the thermal properties of nanostructured silicon membranes using a near field technique.
